Perfumery expert Lu Chen spends three years recreating ancient Eastern dragon's-blood incense, only to be betrayed by his fiancée, Su Muxue, and Bai Zihang, a returnee from overseas. They steal his formula and drive him out. He takes the essential fragrance primer with him, turning the villains' product launch into an international laughingstock and sending their company rapidly into bankruptcy. Lu Chen finds long-lost rare Qinan agarwood on the black market and uses ancient extraction methods to create exquisite fragrances that amaze the world, establishing a domestic fragrance group. When his enemies try to pass off inferior synthetic fragrances as comparable products, they are exposed in public. Ultimately, Lu Chen brings the ancient Eastern art of perfumery to the world stage and establishes an intangible cultural heritage base to preserve a thousand years of incense culture.
